Effects Of Exercise Training On Muscle Quality In Older Individuals: A Systematic Scoping Review With Meta-Analyses, Tibor Hortobágyi, Tomas Vetrovsky, Jennifer S. Brach, Martijn Van Haren, Krystof Volesky, Regis Radaelli, Pedro Lopez, Urs Granacher

Research outputs 2022 to 2026

Background: The quantity and quality of skeletal muscle are important determinants of daily function and metabolic health. Various forms of physical exercise can improve muscle function, but this effect can be inconsistent and has not been systematically examined across the health-neurological disease continuum. The purpose of this systematic scoping review with meta-analyses was to determine the effects and potential moderators of exercise training on morphological and neuromuscular muscle quality (MMQ, NMQ) in healthy older individuals. In addition and in the form of a scoping review, we examined the effects of exercise training on NMQ and MMQ in individuals with neurological …

Time To Consider The Potential Role Of Alternative Resistance Training Methods In Cancer Management?, Francesco Bettariga, Chris Bishop, Dennis R. Taaffe, Daniel A. Galvão, Luca Maestroni, Robert U. Newton

Research outputs 2022 to 2026

Exercise has emerged as fundamental therapeutic medicine in the management of cancer. Exercise improves health-related outcomes, including quality of life, neuromuscular strength, physical function, and body composition, and it is associated with a lower risk of disease recurrence and increased survival. Moreover, exercise during or post cancer treatments is safe, can ameliorate treatment-related side effects, and may enhance the effectiveness of chemotherapy and radiation therapy. To date, traditional resistance training (RT) is the most used RT modality in exercise oncology. However, alternative training modes, such as eccentric, cluster set, and blood flow restriction are gaining increased attention. These training modalities …

Neuromuscular Adaptations To Different Set Configurations During A Periodized Power Training Block In Elite Junior Judokas, Dale M. Harris, Dustin J. Oranchuk, Christopher Latella

Research outputs 2022 to 2026

Although the impacts of traditional sets (TS) versus cluster (CL) sets resistance training have been broadly explored among recreationally trained populations, no studies have previously compared these set configurations among elite Judokas. Twenty-two elite male and female Judokas (age = 17.5 ± 1.2 years) performed identical periodized 4-week hypertrophy and strength blocks (8 weeks in total). Following this, for the final 4-week power training block, the cohort was separated into either TS (n = 11) or CL (n = 11) set structures. CL were prescribed by including 45-second intra-set rest every two repetitions. One-repetition maximum (1RM) and peak barbell velocities …

Study Protocol: Investigating The Feasibility Of A Hybrid Delivery Of Home-Based Cluster Set Resistance Training For Individuals Previously Treated For Lung Cancer, C. M. Fairman, O. L. Owens, Kristina L. Kendall, J. Steele, Christopher Latella, M. T. Jones, L. Marcotte, Carolyn M. J. Peddle-Mcintyre, K. K. Mcdonnell

Research outputs 2022 to 2026

Background: Symptom burden remains a critical concern for individuals with non-small cell lung cancer (NSCLC) following the completion of treatment. The most common symptom clusters, dyspnea (shortness of breath) and fatigue, can contribute to physical decline, reductions in quality of life, and a higher risk of comorbidities and mortality. Dyspnea is a primary limiter of exercise capacity in individuals with lung cancer, resulting in exercise avoidance and an accelerated physical decline. As such, designing resistance training with cluster sets to mitigate symptoms of dyspnea and fatigue may result in improved exercise tolerance. Thus, maintaining the exercise stimulus via cluster sets, …

Feasibility And Acceptability Of A Remotely Delivered, Home-Based, Pragmatic Resistance ‘Exercise Snacking’ Intervention In Community-Dwelling Older Adults: A Pilot Randomised Controlled Trial, Jackson J. Fyfe, Jack Dalla Via, Paul Jansons, David Scott, Robin M. Daly

Research outputs 2022 to 2026

Background: Very few older adults meet current muscle strengthening exercise guidelines, and several barriers exist to supervised, community-based resistance exercise programs. Older adults therefore require access to feasible resistance exercise modalities that may be performed remotely. This pilot study assessed the feasibility and acceptability of undertaking a four-week home-based resistance ‘exercise snacking’ intervention (performed either once, twice, or thrice daily) when delivered and monitored remotely in older adults. Methods: Thirty-eight community-dwelling older adults [mean ± SD age 69.8 ± 3.8 y, 63% female] were randomised to complete resistance ‘exercise snacks’ (9-minute sessions) either once (n = 9), twice (n = …

Comparison Of Weightlifting, Traditional Resistance Training And Plyometrics On Strength, Power And Speed: A Systematic Review With Meta-Analysis, Stephanie J. Morris, Jon L. Oliver, Jason S. Pedley, G. Gregory Haff, Rhodri S. Lloyd

Research outputs 2022 to 2026

Background:

Weightlifting training (WLT) is commonly used to improve strength, power and speed in athletes. However, to date, WLT studies have either not compared training effects against those of other training methods, or been limited by small sample sizes, which are issues that can be resolved by pooling studies in a meta-analysis. Therefore, the objective of this systematic review with meta-analysis was to evaluate the effects of WLT compared with traditional resistance training (TRT), plyometric training (PLYO) and/or control (CON) on strength, power and speed.

Methods:

The systematic review included peer-reviewed articles that employed a WLT intervention, a comparison group …

Effects Of Variations In Resistance Training Frequency On Strength Development In Well-Trained Populations And Implications For In-Season Athlete Training: A Systematic Review And Meta-Analysis, Matthew Cuthbert, G. Gregory Haff, Shawn M. Arent, Nicholas Ripley, John J. Mcmahon, Martin Evans, Paul Comfort

Research outputs 2014 to 2021

Background: In-season competition and tournaments for team sports can be both long and congested, with some sports competing up to three times per week. During these periods of time, athletes need to prepare technically, tactically and physically for the next fixture and the short duration between fixtures means that, in some cases, physical preparation ceases, or training focus moves to recovery as opposed to progressing adaptations. Objective: The aim of this review was to investigate the effect of training frequency on muscular strength to determine if a potential method to accommodate in-season resistance training, during busy training schedules, could be …

Autoregulation In Resistance Training: Addressing The Inconsistencies, Leon Greig, Ben Hayden Stephens Hemingway, Rodrigo R. Aspe, Kay Cooper, Paul Comfort, Paul A. Swinton

Research outputs 2014 to 2021

© 2020, The Author(s). Autoregulation is a process that is used to manipulate training based primarily on the measurement of an individual’s performance or their perceived capability to perform. Despite being established as a training framework since the 1940s, there has been limited systematic research investigating its broad utility. Instead, researchers have focused on disparate practices that can be considered specific examples of the broader autoregulation training framework. A primary limitation of previous research includes inconsistent use of key terminology (e.g., adaptation, readiness, fatigue, and response) and associated ambiguity of how to implement different autoregulation strategies. Crucially, this ambiguity in …

Isokinetic Eccentric Exercise Substantially Improves Mobility, Muscle Strength And Size, But Not Postural Sway Metrics In Older Adults, With Limited Regression Observed Following A Detraining Period, Anthony David Kay, Anthony John Blazevich, Millie Fraser, Lucy Ashmore, Mathew William Hill

Research outputs 2014 to 2021

© 2020, The Author(s). Introduction: Eccentric exercise can reverse age-related decreases in muscle strength and mass; however, no data exist describing its effects on postural sway. As the ankle may be more important for postural sway than hip and knee joints, and with older adults prone to periods of inactivity, the effects of two 6-week seated isokinetic eccentric exercise programmes, and an 8-week detraining period, were examined in 27 older adults (67.1 ± 6.0 years). Methods: Neuromuscular parameters were measured before and after training and detraining periods with subjects assigned to ECC (twice-weekly eccentric-only hip and knee extensor contractions) or …

Velocity-Based Training: Monitoring, Implementation And Effects On Strength And Power, Henry G. Banyard

Theses: Doctorates and Masters

Traditionally, resistance training has been prescribed using percent-based training (PBT) methods that use the loads relative to a maximal load lifted for one repetition (1RM). However, PBT does not take into account possible day-to-day fluctuations in performance that may occur from physical or psychological stressors. One approach to address this limitation is to monitor velocity changes during resistance training, based on research showing that declines in velocity are highly correlated with fatigue. Therefore, velocity-based training (VBT) methods are proposed to provide a more objective method to modify resistance training sessions based on individual differences in day-to-day performance and the rate …

Research outputs 2014 to 2021

BACKGROUND: Skeletal metastases present a major challenge for clinicians, representing an advanced and typically incurable stage of cancer. Bone is also the most common location for metastatic breast carcinoma, with skeletal lesions identified in over 80% of patients with advanced breast cancer. Preclinical models have demonstrated the ability of mechanical stimulation to suppress tumour formation and promote skeletal preservation at bone sites with osteolytic lesions, generating modulatory interference of tumour-driven bone remodelling. Preclinical studies have also demonstrated anti-cancer effects through exercise by minimising tumour hypoxia, normalising tumour vasculature and increasing tumoural blood perfusion. This study proposes to explore the promising …

Assessment Of Joint Kinetics In Elite Sprint Cyclists, Lynne Munro

Theses: Doctorates and Masters

Sprint cycling requires the production of explosive muscle power outputs up to very high pedalling rates. The ability to assess muscular function through the course of the sprint would aid training practices for high-level performers. Inverse dynamics provides a non-invasive means of estimating the net muscle actions acting across any joint contributing to movement. However, analysis of joint kinetics requires motion-capture techniques that present some unique challenges for cycling. This thesis presents three studies investigating the application of a custom-designed force pedal system to examine the joint kinetics of elite trained track sprint cyclists. To provide the basis for selecting …

Comparison In Muscle Activity Between The Back Squat, Romanian Deadlift And Barbell Hip Thrust During Hip Extension, Jose Delgado

Theses: Doctorates and Masters

Common resistance-training exercises such as back squat, Romanian deadlift (RDL), and hip thrust have been used by strength and conditioning specialists to target the musculature used during hip extension. Little is known about the differences in muscular activity of the hip extensors between these exercises, so it is not known which is the most effective as a hip extensor exercise. The primary purpose of this study was to compare muscle activity of several muscles during the high-bar back squat, RDL and barbell hip thrust, using men with a minimum of 1 year of lower-body resistance-training experience. Surface electromyography (EMG) was …

Greater Strength Gains After Training With Accentuated Eccentric Than Traditional Isoinertial Loads In Already Strength-Trained Men, Simon Walker, Anthony J. Blazevich, Greg Haff, James J. Tufano, Robert Newton, Keijo Häkkinen

Research outputs 2014 to 2021

As training experience increases it becomes more challenging to induce further neuromuscular adaptation. Consequently, strength trainers seek alternative training methods in order to further increase strength and muscle mass. One method is to utilize accentuated eccentric loading, which applies a greater external load during the eccentric phase of the lift as compared to the concentric phase. Based upon this practice, the purpose of this study was to determine the effects of 10 weeks of accentuated eccentric loading vs. traditional isoinertial resistance training in strength-trained men. Young (22 ± 3 years, 177 ± 6 cm, 76 ± 10 kg, n = …
